The invention relates to a clamping device for an injection molding machine for plastics, including a fixed platen (11) which is connected to a moving platen (12) by means of a toggle mechanism (13). A hollow-shaft motor (7) is provided to cooperate with a spindle (21) for operating the toggle mechanism, wherein the hollow-shaft motor (7) is connected to the toggle mechanism (13). According to the invention, the spindle (21) is arranged in a rotationally fixed manner, the end of the spindle (21), facing the moving platen (12), is in engagement with the rotor (6) of the hollow-shaft motor (7), and the stator (4) of the hollow-shaft motor is connected with the toggle mechanism (13). Preferably, a spindle nut is fixed in the rotor (6) for engagement with the spindle (21), preferably in the form of a recirculating ball screw.
Clamping device for an injection molding machine for plastics, comprising a fixed paten, which is connected via a toggle mechanism with a moving platen, wherein a hollow-shaft motor interacts with a spindle for operating the toggle mechanism, and wherein the hollow-shaft motor is connected with the toggle nechanism, characterized in that the spindle (21) is arranged in rotationally fixed manner, that the end of the spindle (21), facing the moving platen (12), is in engagement with the rotor (6) of the hollow-shaft motor (7), and that the stator (4) of the hollow-shaft motor is connected with the toggle mechanism (13).
